1928. Serial -water, or by any other suitable after treat mentJ'Theinvention disclosed herein is especially usefulin'a roaster of the typedisclosed and claimed in .apatent for pi niento roasters, No. 1,660,061,filed March 7, 1927, the present application The objects of thisinvention are: first, to

provide aaroas'terfhavingi a'conveyor which.

travels through a tunnel-like oven, in which it is subjected to heat andwhich conveyor is i N .,neatl1 it on suitable idlers- 16. Between thecooled in its transit through the oven so as to prevent damage thereto;second, to provide a conveyor of the endless type which rides throughthe oven on rails which are cooled to keep the temperature of theconveyor below 1 the point at which damage might occur to it; and third,to provide details of structure whereby asimple, economical, efficientand long l1ved structure is obtained.

Other objects and advantages will be made fully apparent from thefollowing specifica- A tionjconsidered in connection with theaccompanying drawings, in which:

Fig. l is an elevation of a roaster const'ruct ed in accordance with myinvention; Fig. 2

is a cross section of the roaster on an enlarged scale as seen on theline 22 of Fig. 1 Fig.

3 is a fragmentary longitudinal section on an enlarged scale as seen onthe line 33 of Fig. 2' 2, showing'details'of the carrier chain; and

Fig. 4 is a cross section of one of the carrier chains, as seen on theline 4-4: of Fig. 3.

Referring with more particularity tothe drawings, the roaster comprisesa tunnellike oven structure 5 of fire brick or similar heat resistingmaterial, supported and tied together with a suitable iron frame work 6.

The oven is open at the ends and is provided secured, as-by rivets 20, asemi-circular shell w vtogether inspaced relationship arepipes 23 FEE iwith a series of openings 7 in its sides, rows on one side preferablybeing'in staggered relation to those on the other, side. Extendinglongitudinally along each side of the oven and supported onsuitable-bracketssecured to the frame work of the oven are gaspipes 8 towhich are connected burners 9 projecting inwardy through the openings inthe side Walls of the oven. A chimney 10 is mounted on the .oven roof tocarry oifthe products-of driven from a counter shaft 12. A shaft andsimilar sprocket wheels 13 are supportedfat the opposite ends of theoven, adjustment 0 n I combustion. Mounted 1n bearings on one end of theframe work 6 is a shaft carrying a pair of sprocket wheels 11 andarranged to be means to move the shaftin ahorizontal direc chains withintheoven irs a; parapet wall or curb 17,-preferably of the same materialas the oven and having'a rounded top.

As the chains are similar, only one will be described. It consistsof anumber of links 18 pivotally secured together, each link havingvoutstanding arms 19 at the sides, to which is:-'

21, preferably formed ofsheetmetal and hav-.

ng. an upstanding lip 22at one end. Supported; on "the floor of; theoven and secured and 24. Thesesupport'the chainwhich-slides g thereon onthe heads of rivets 20, the sides of thelinks 18 serving'to hold it inplace later-- ally. The wear incidentto the, sliding of the chains,through the oven on the pipes is taken when necessary- These pipes are"provided 190 T by these rivets, which may be easilyreplaced f withsuitable connections not shown, whereby,

circulation of waterorcooling fluid may be mainta ned through them. 1

The gas from theburners having beenignited 1 The operation ofthe'roaster. isasi follows: I,

the individual pieces. These lie partly on the shells 21 of oneor theother'chain and partly ionthe wall 17 as clearly shown in Fig. 2. As thechains advance into and through the oven,

the lips 22 move the fruit along with them into the oven. whereit is"exposed to the flames issuing from the burners 9. Fruit being sub;stanti'ally spheroidal in shape and by reason of resting partly on themoving chain and partly on the stationary wall, is rolled or turned invarious directions as it advances,

' thuscontinually exposing fresh parts of the surface to -the action ofthe flames. The fruit after having been conveyed to the oven is dis- 0charged at the opposite end from that which it enters, where it may beremoved from the chains-by hand or other suitable means. It

is then ready for further treatment.

The portions of the chains within the oven will be subjected to the heatof the flames and liable to damage as a result. The chains ride throughthe furnace on pipes 23, forming rails as before' des'cribed, which arekept cool by v circulating cooling fluid such as water [through them asby a pump 24. As the chains are in contact with the pipe rails, aportion of the'heat absorbed by the former will be conducted away'by thelatter, which results.

in keeping the temperature'of the chains bei low the point at whichdamage might occur.

What I claim is z t 1, A device of the character described ineluding anoven, heating means for said oven, 7 a carrier chain disposed to travelthrough comprising a pair of laterally spaced pipes adapted toslidablyengage therivets in said arms whereby the wear incident to saidlinks riding over said pipe is taken by said rivets and heattransferredbetween said chain and pipes, and means to pass cooling fluidthrough said pipe whereby the temperature of said pipes and sa'id'chainsaremaintained below the temperature of said oven.

4. The combination of a carrier chain, comprisinglinks, each linkincluding a pair of outstanding arms, a curved shell secured to saidoutstanding arms by means of rivets,

tubular guide rails for said chain supporting 7 said arms and slidablyengaged with rivets, whereby the wear incident to said links being movedover said rails is takenby said rivets and heat transferred between saidchain and rails, said guide rails being adapted to have cooling fluidpassed therethrough.

5. Thecombination of a carrier chain comprising links, each link havinga pair of outstanding arms, a curvedshell secured to said outstandingarms'by means of rivets, tubular guide rails for said'chain comprising apair of laterally spaced pipes adapted to support said arms and slidablyengaged with said rivet-s whereby the wear incident to said'links beingmoved over said pipe is taken by said rivets, and means to pass coolingfluid through said pipe.
